Thomas Betts B-100-1/4 Short Spring Nut 1/4 in Strut

Product Description

The THOMAS BETTS B-100-1/4 is a short spring nut designed for use with strut channel systems. It provides a secure, adjustable fastening point within the channel track, allowing threaded fasteners to be positioned and repositioned without disassembling the channel. Constructed from steel with an electro galvanized finish, it resists corrosion in typical indoor mechanical and electrical installations. The nut accepts a 1/4-20 threaded bolt and is rated for use exclusively with Thomas Betts Channel Type B. Electricians and mechanical contractors use this hardware when securing conduit, pipe hangers, cable trays, and equipment to strut channel support systems.

This short spring nut is suited for residential and commercial electrical, HVAC, and plumbing support applications where strut channel is used as the primary structural support. It fits into Channel Type B strut track and holds position until a bolt is tightened, which speeds up layout and adjustment during installation. Cross-reference part numbers include Unistrut P4006-1420 and B-Line N524, making it a compatible replacement option across multiple strut channel product lines where those designations apply.
